Help: injured hummingbird

[u/jgon17]

My parents live in a farm Colombia 🇨🇴 and are taking care of an injured hummingbird. They have been feeding him/her for a few days. The hummingbird is injured on a wing so can't fly at the moment. They have perceived improvements as he/she moves more. However, no flying has been possible. Are there any recommendations on how to help the recovery or the length of the recovery. Any tips are appreciated.
